Study Description

Adamantinomatous Craniopharyngioma (ACP) is a highly debilitating pediatric brain tumor that lacks medical anti-tumor therapies. Current therapy, which depends largely on surgery and radiation, is associated with poor quality of life and becomes more challenging and risky in the setting of recurrent disease. Recent discoveries regarding the biological characteristics of ACP indicate that available agents, including Mitogen-activated protein kinase/extracellular signal-regulated kinase (MAPK/ERK) pathway inhibitors may have efficacy in the control of ACP. Binimetinib is one such agent.

In this study, up to 38 patients will receive oral binimetinib at the recommended phase 2 pediatric dose (RP2D) of 32 mg/m2/dose PO every 12 hours for 4 weeks which represents one cycle. Cycles will last 28 days and treatment may continue for up to two years (26 cycles).

It will be a multi-center Phase 2 trial with two strata for patients aged >1 year and <25 years with measurable ACP who may have been previously treated with radiation (Stratum 1, 18 patients) or without radiation (Stratum 2, 18 patients).

Study Description

This phase III trial studies if selumetinib works just as well as the standard treatment with carboplatin/vincristine (CV) for subjects with NF1-associated low grade glioma (LGG), and to see if selumetinib is better than CV in improving vision in subjects with LGG of the optic pathway (vision nerves). Selumetinib is a drug that works by blocking some enzymes that low-grade glioma tumor cells need for their growth. This results in killing tumor cells. Drugs used as chemotherapy, such as carboplatin and vincristine, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. It is not yet known whether selumetinib works better in treating patients with NF1-associated low-grade glioma compared to standard therapy with carboplatin and vincristine.

 

PRIMARY OBJECTIVES:

I. To determine whether the efficacy of treatment with selumetinib sulfate (selumetinib) as measured by event-free survival (EFS) is non-inferior to treatment with carboplatin/vincristine sulfate (vincristine) (CV) in previously untreated neurofibromatosis type 1 (NF1)-associated low-grade glioma (LGG).

II. To determine whether visual acuity (VA) using Teller acuity cards (TAC), in patients with NF1-associated LGG within the optic pathway, is better in those treated with selumetinib compared to CV.

 

SECONDARY OBJECTIVES:

I. To estimate tumor response rates and overall survival (OS) in each treatment regimen in previously untreated NF1-associated LGG.

II. To evaluate VA outcomes utilizing HOTV letter acuity testing in previously untreated NF1-associated LGG within the optic pathway in patients who are old enough to perform visual acuity testing utilizing HOTV (a recognition acuity measure).

III. To describe the improvement in motor function as measured by the Vineland scale in patients with previously untreated NF1-associated LGG that have documented motor deficits at enrollment.

IV. To prospectively evaluate and compare the quality of life among patients treated with selumetinib or CV.

V. To prospectively evaluate and compare the cognitive, social, emotional, and behavioral functioning of patients with NF1-associated LGG treated with either selumetinib or CV.

 

EXPLORATORY OBJECTIVES:

I. To evaluate optical coherence tomography (OCT) measures of retinal axon and ganglion cell thickness as a marker of treatment response in previously untreated NF1-associated LGG within the optic pathway.

II. To compare novel, semi-automated volumetric magnetic resonance imaging (MRI) measures to traditional measurements of treatment response (bi-dimensional MRI measurements) in NF1-associated optic pathway tumors.

III. To obtain paired blood and tumor tissue to be banked for future NF1-LGG biology studies involving comprehensive molecular analysis, including but not limited to whole exome and ribonucleic acid (RNA) sequencing.

OUTLINE: Patients are randomized to 1 of 2 arms.

ARM I:

INDUCTION: Patients receive carboplatin intravenously (IV) over 60 minutes on days 1, 8, 15, 22, 43, 50, 57, and 64 and vincristine IV or IV push over 1 minute on days 1, 8, 15, 22, 29, 36, 43, 50, 57, and 64 in the absence of disease progression or unacceptable toxicity. Patients also undergo MRI during screening and on study.

MAINTENANCE: Patients receive carboplatin IV over 60 minutes on days 1, 8, 15, and 22 and vincristine IV or IV push over 1 minute on days 1, 8, and 15. Treatment repeats every 6 weeks for 8 cycles in the absence of disease progression or unacceptable toxicity. Patients also undergo MRI on study and during follow-up.

ARM II: Patients receive selumetinib sulfate orally (PO) twice daily (BID) on days 1-28. Treatment is continuous and repeats every 28 days for 27 cycles in the absence of disease progression or unacceptable toxicity. Patients also undergo MRI throughout the trial.

Study Description

 

 This study is eligible for STEP-1 funding. Find more information here

This is a Phase I study to evaluate the safety profile of a type of immune therapy called HER2 CAR T cells (short for HER2 chimeric antigen receptor T cells). In addition to looking for side effects, we will study how well this treatment works against a brain tumor called ependymoma that has come back after treatment (recurrent) or has not responded well to treatment (progressive) in children. The HER2 CAR T cells used in this trial are made from the patient's own blood. A new gene, called the HER2 CAR, will be inserted into patient's T cells to allow them recognize a protein on the tumor called HER2. These HER2-specific CAR T cells may be able to target and kill ependymoma tumors that express HER2. This research is also studying how doable it is to provide this type of CAR T cell treatment to children being treated at different hospitals.

The primary objectives of the Phase I study are to determine the safety of intravenous injection of HER2-specific CAR T cells after lymphodepleting chemotherapy, and to evaluate the multicenter feasibility of administering up to three infusions of HER2-CAR T cells after lymphodepletion.

Patients will receive one infusion of HER2psecific CAR T cells after lymphodepleting chemotherapy. Following recovery from their first treatment (no earlier than 8 weeks and no later than 12 weeks), patients will resume treatment with HER2-specific CAR T cells for up to 2 infusions after lymphodepleting chemotherapy if they meet laboratory parameters. The length of time on study for patients enrolled on the Phase I study is anticipated to be 9 months on treatment. Patients will then be followed for 15 years after treatment.

Surgical Study

The objective of the Surgical study is to evaluate the post-treatment tumor tissue for presence of HER2-specific CAR T cells administered intravenously in children undergoing surgical resection. The surgical study will be initiated following completion of the safety evaluation period of 6 patients treated in the Phase I study.

Once the surgical study is open for enrollment, all patients who have clinical indication for surgery, except those needing urgent surgery, will be eligible for enrollment to the surgical study. Patients will receive one infusion of HER2-specific CAR T cells after lymphodepleting chemotherapy 4-6 weeks before surgical resection of their tumor, at which time samples will be taken for analysis. Following recovery from surgery (no earlier than 8 weeks and no later than 15 weeks), patients will resume treatment with HER2-specific CAR T cells for up to 2 infusions if they meet laboratory parameters.

The first patient in the surgical study will complete a 6-week safety evaluation period prior to enrollment of the subsequent patient. The length of time on study for patients enrolled on the Surgical study is anticipated to be 10 months on treatment. Patients will then be followed for 15 years after treatment.

Dosing

All patients on Phase I and Surgical study will receive HER2 CAR T cells at a patient-specific dose level 1 (8x10^7 CAR-positive T cells/m^2) for infusion. The cell dose will be based on the patient weight and height obtained by the treating institution at the time of procurement. For patients whose BMI is greater than 95th percentile for given age and sex, the Body surface area (BSA) will be calculated using the ideal body weight.

In the event that dose level 1 is found to have excessive toxicity, three additional doses of CAR T cells at dose level -1 (5x10^7 CAR-positive T cells/m^2) will be made to be used in the event that dose de-escalation occurs before a patient is enrolled for treatment.

    • Patients who meet eligibility criteria per Section 3.3.1.2.2 must be enrolled using Surgical Study treatment consent (Stratum 2).

 

Please note there is additional criteria for screening, outlined below: 

  1. Tumor: Patient must have a diagnosis of ependymoma that is recurrent or progressive. All tumors must have histologic verification either at the time of diagnosis or recurrence.

  2. Prior Therapy: Patient must have received standard of care therapy including maximal safe surgical resection followed by local adjuvant radiation therapy prior to enrollment.

  3. Adequate Pre-trial Tumor Tissue: Patient must have adequate pre-trial tumor material available to determine HER2 status. Tumor tissue from the most recent resection or biopsy of recurrent disease in preferred. If unavailable, tumor tissue from prior recurrences or from the time of initial diagnosis is acceptable.

    a. One exception will be patients who have previously received HER2-directed therapy (including but not limited to trastuzumab); these patients will need evaluation of tumor HER2 status after stopping treatment due to the possibility of HER2 downregulation or loss. Tumor biopsy will not be performed for the purpose of HER2 screening. Patients will not be eligible for screening on PBTC-059 if tumor tissue is not available or inadequate for HER2 testing. Tumor screening by Immunohistochemistry (IHC) will be done centrally using the testing method validated at Texas Children's Hospital. Sample for screening must be shipped within 7 days of enrollment for screening.

  4. Known HIV Positivity: Patients that are known to be HIV-positive are ineligible due to the unknown safety and efficacy of infusing these patients with CAR T cells genetically modified using retroviral vectors. Additionally, the immunosuppression used for treatment in this study will pose an unacceptable risk.

  5. Age: Patient must be ≥ 1 but ≤ 21 years of age at the time of screening consent.

  6. Screening Consent: The patient or parent/guardian can understand the consent and is willing to sign a written informed consent document according to institutional guidelines. Age- and developmentally appropriate assent should be obtained as required by institutional guidelines.

  7. Potential Eligibility for Study Treatment Enrollment: Patients are screened for this trial should be reasonably anticipated to meet the criteria for treatment described in Section 3.3 if their tumor is HER2-positive.

Study Description

 

Brief Summary:

This is a pilot study that will evaluate disease status in children that have been newly diagnosed high-grade glioma with TRK fusion. The evaluation will occur after 2 cycles of the medication (Larotrectinib) have been given. The study will also evaluate the safety of larotrectinib when given with chemotherapy in your child; as well as the safety larotrectinib when given post-focal radiation therapy.

Detailed Description:

In this pilot study, we will assess the disease control rate (Continued Complete Response-CCR, Complete Response-CR, Partial Response-PR and Stable Disease-SD) as well as survical rate (overall survival- OS and progression free survival- PFS) in children with newly diagnosed HGG with TRK fusion who receive 2 cycles of larotrectinib monotherapy administered orally, twice daily, at 100 mg/m2 continuously on a 28-day cycle schedule. After 2 monotherapy cycles of larotrectinib, patients with CCR or CR will continue to receive larotrectinib maintenance therapy as monotherapy for a total of 12 cycles. Patients ≤ 48 months with PR or SD after 2 cycles of larotrectinib will go on to receive combination therapy with standard backbone chemotherapy (BABYPOG or HIT-SKK). Patients > 48 months of age (or patients ≥ 36 months of age, or patients with DIPG >18 months of age, at the discretion of the local investigator) will receive focal radiation therapy. A surgical cohort study will be explored whereby patients who have had a tumor biopsy/partial resection at their local institution and are planned to subsequently undergo definitive resection will receive 3-5 days (6-10 doses) of larotrectinib pre-surgery.

The study design of this trial requires 15 patients evaluable for disease control and for safety/ toxicity of larotrectinib as monotherapy. The surgical cohort will enroll up to 4 patients and will count towards the total 15 evaluable patients. A minimum of 6 patients will be evaluable for safety toxicity of larotrectinib in combination with standard-of-care chemotherapy or radiotherapy.

Inclusion Criteria
  • Age: Patients ≤ 21 years of age (birth to 21 years of age) at the time of study enrollment will be eligible.
  • Diagnosis: Patients with newly-diagnosed high-grade (HGG), including diffuse intrinsic pontine gliomas (DIPG), whose tumors are documented in a CLIA/CAP certified lab (or clinically equivalent method considered standard in non-US sites) to harbor an NTRK fusion alteration by FISH, PCR, or next generation sequencing are eligible. Patients must have had histologically verified high-grade glioma such as anaplastic astrocytoma, glioblastoma, or H3 K27-mutant diffuse midline glioma verified at a CONNECT site.

For sites that do not have CLIA-certified equivalent (certified laboratory) to assess NTRK fusion, testing will be conducted centrally at NCH. NTRK testing will be performed by NGS using targeted RNA-sequencing (Archer Solid Tumor analysis) Please submit 10 unstained sections on charged slides at 10uM thickness, or 10 scrolls cut at 10uM thickness, along with submission of an H&E slide. Formalin-fixed paraffin embedded (FFPE) tissue block and FFPE tissue scroll specimens must contain minimum of 25% tumor Snap-frozen tissue specimens are also acceptable and they must contain a minimum of 10% tumor. Please note that turn-around time for this test is up to 21 days.

  • Disease Status: Patients with disseminated DIPG or HGG are eligible only if the patient is to receive chemotherapy only, i.e. no craniospinal RT is intended to be given. MRI of spine must be performed if disseminated disease is suspected clinically by the treating physicians. Patients with primary spinal tumors are eligible only if the patient is to receive either chemotherapy or focal radiation therapy, i.e. no craniospinal RT is intended to be given. Patients with leptomeningeal disease only, with no definitive identifiable primary tumor, and documented NTRK fusion, must be discussed with the Study Chair on a case-by-case basis.
  • Surgical Cohort ONLY: Patients with newly-diagnosed HGG with NTRK fusions who have undergone prior biopsy and for whom further resection is indicated for a more definitive surgery at an enrolling site will be eligible to enroll onto the surgical study. DIPG patients are not eligible for the surgical cohort.
  • Performance Level: Karnofsky ≥ 50% for patients > 16 years of age and Lansky ≥ 50 for patients ≤ 16 years of age (See Appendix I). Patients who are unable to walk because of paralysis, but who are up in a wheelchair, will be considered ambulatory for the purpose of assessing the performance score.

Study Description

 

Brief Summary:

Quizartinib is an experimental drug. It is not approved for regular use. It can only be used in medical research.

Children or young adults with a certain kind of blood cancer (FLT3-ITD AML) might be able to join this study if it has come back after remission or is not responding to treatment.

Detailed Description:

The medical condition being investigated is relapsed or refractory AML in participants aged ≥1 month to ≤21 years with Feline McDonough Sarcoma (FMS)-like tyrosine kinase 3 (FLT3)-internal tandem duplication (ITD) mutations (FLT3-ITD AML), following failure of front-line intensive chemotherapy.

The trial will be conducted in multiple phases. An independent data monitoring committee (DMC) will protect the rights, safety, and well-being of participants by monitoring the progress and results. The DMC will comprise qualified physicians and scientists who are not Investigators in the study and not otherwise directly associated with the Sponsor and will be convened at the end of Phase 1.

A. Dose Escalation/De-escalation Phase:

Number of participants is determined by age group. Participants will be enrolled by dose-level to determine the recommended Phase 2 dose (RP2D) of quizartinib for pediatric participants that provides similar exposure to adult patients treated at the target adult dose of 60 mg orally once daily.

B. Dose-Expansion Phase:

Participants will receive the RP2D of quizartinib for their respective age group.

During both dose escalation and dose expansion phases, participants will receive:

Re-Induction Therapy

  • Intrathecal (IT) triple chemotherapy prophylaxis prior to and between cycles
  • In re-induction Cycles 1 and 2, fludarabine/cytarabine (FLA) followed by quizartinib as a single agent

Allogeneic Hematopoietic Stem Cell Transplantation (HSCT) Period:

After re-induction therapy, participants will be evaluated for eligibility to undergo allogeneic hematopoietic stem cell transplant (HSCT). Eligible participants may receive a single 28-day cycle of consolidation therapy (standard of care chemotherapy with or without quizartinib) if an allogeneic HSCT is not available immediately. The options for consolidation therapy are as follows:

  • High intensity chemotherapy with quizartinib, or
  • Low intensity chemotherapy alone, or
  • Low intensity therapy with quizartinib as a single agent

Continuation Therapy:

Participants in remission after HSCT, or who are not eligible for HSCT but achieve at least a partial remission (PR) after re-induction, will receive up to 12 continuous 28-day cycles of quizartinib continuation therapy at the same dose received during re-induction in the dose expansion phase.

Long-term Follow-up:

The long-term follow-up phase begins upon completion of 12 cycles of quizartinib Continuation Therapy or permanent discontinuation of quizartinib at any time. After completion of the 30-day safety follow-up visit, subsequent visits will occur at the following frequencies to assess survival and anti-leukemic treatments:

  • every 3 months for the first 2 years, and then
  • once a year thereafter until the last participant enrolled has been followed for three years from the date of enrollment
Inclusion Criteria
  • Has diagnosis of AML according to the World Health Organization (WHO) 2008 classification with >5% blasts in bone marrow, with or without extramedullary disease
  • Is in first relapse or refractory to first-line high-dose chemotherapy with no more than 1 attempt (1 to 2 cycles of induction chemotherapy) at remission induction - prior HSCT is permitted

Study Description

 

This is a Pilot, multicenter, open-label study of patients less than or equal to 25 years, with recurrent or progressive LGG harboring a CRAF or BRAF alteration, including BRAF V600 mutations and KIAA1549: BRAF fusions. Patients with BRAF or CRAF alterations will be identified through molecular assays as routinely performed at Clinical Laboratory Improvement Amendments (CLIA) of 1988 or other similarly certified laboratories.

The study will be conducted in two sequential phases:

Phase A: A Feasibility (combination dose finding) phase, followed by Phase B: An Efficacy phase. The maximum tolerated dose (MTD)/Recommended Phase 2 Dose (RP2D) of the combination as determined in Phase A would be the dose used in Phase B. The patients on Phase A who were below the MTD/RP2D would be eligible for intra-patient dose escalation to MTD/RP2D subject to criteria outlined later.

____________________________

Phase A (Feasibility Phase) - Open at SickKids

A feasibility phase will be conducted to establish the maximum tolerated dose (MTD/RP2D) of the combination of vinblastine + tovorafenib using the Rolling 6 design.

Patients will receive vinblastine and tovorafenib on Days 1, 8, 15, 22 of each cycle for a total duration of 17 cycles followed by 7 additional cycles of tovorafenib alone. One cycle of protocol therapy is 28 days.

Treatment cycles will repeat every 28 days for a total of 24 cycles in the absence of disease progression or unacceptable toxicity. Patients will undergo radiographic evaluation of their disease at the end of every third cycle, starting with the end of Cycle 3.

The RP2D of tovorafenib of 420 mg/m2 once weekly (not exceeding 600 mg) in combination with vinblastine (4mg/m2) will be used as the starting dose and will be de-escalated/escalated as per Table 4. Dose of tovorafenib will not be escalated further.

Patients will be treated on protocol therapy for a total of 24 cycles, the vinblastine and tovorafenib for a total duration of 17 cycles followed by 7 additional cycles of alone tovorafenib, unless disease progression, unacceptable toxicity occurs, or withdrawal from the study occurs. Missed doses of either vinblastine or tovorafenib will not be made up.

Phase B (Expansion/Efficacy Phase) - Not Yet Open

Once the MTD/RP2D of the combination, vinblastine + tovorafenib has been established, the expansion/efficacy phase will be initiated at the dose determined in Phase A.

Patient will receive vinblastine and tovorafenib weekly on Days 1, 8, 15, 22 of each cycle at dose determined in Phase A for a total duration of 17 cycles followed by 7 additional cycles of tovorafenib alone. One cycle of protocol therapy is 28 days.

Treatment cycles will repeat every 28 days in the absence of disease progression or unacceptable toxicity. Patients will undergo radiographic evaluation of their disease at the end of every third cycle, starting with the end of Cycle 3.

Patients will be treated on protocol therapy for a total of 24 cycles, the vinblastine and tovorafenib for a total duration of 17 cycles followed by 7 additional cycles of alone tovorafenib, unless disease progression or unacceptable toxicity occurs, unless disease progression, unacceptable toxicity or withdrawal from study occurs. Missed doses of either vinblastine or tovorafenib will not be made up.

Study Description

 

ACTEMRA (tocilizumab) is an IL-6 receptor antagonist used for the treatment of adult Rheumatoid Arthritis as well as Polyarticular (PJIA) and Systemic (SJIA) Juvenile Idiopathic Arthritis. In this Phase II, the drug will be used to treat pediatric patients diagnosed with recurrent Adamantinomatous Craniopharyngioma including patients who have undergone surgery and/or radiation therapy.

Adamantinomatous Craniopharyngioma (ACP) is a highly debilitating pediatric brain tumor that lacks medical anti-tumor therapies. Current therapy, which depends largely on surgery and radiation, is associated with poor quality of life and becomes more challenging and risky in the setting of recurrent disease. Recent discoveries regarding the biological characteristics of ACP indicate that available agents, including IL-6 pathway blockers may have efficacy in the control of ACP. We hypothesize that the IL6- receptor antagonist ACTEMRA (tocilizumab) will be safe and effective at inducing tumor response in children with residual ACP.

In this study, up to 38 patients will receive tocilizumab at the dose approved for pediatric Systemic Juvenile Idiopathic Arthritis (< 30 kg: 12 mg/kg IV every 2 weeks; ≥30 kg: 8 mg/kg IV every 2 weeks). Therapy may continue for up to two years (26 cycles).

It will be a multi-center Phase 2 trial with two strata for patients aged >1 year and <25 years with unresectable ACP who may have been previously treated with radiation (Stratum 1, 18 patients) or without radiation (Stratum 2, 18 patients).

Inclusion Criteria
  1. Age: Patients must be ≥ 12 months and ≤ 25 years of age at the time of study enrollment.
